Explanation:
Some general comments about gas exchange and diffusion will be made, followed by a description of how oxygen is carried in the blood. The binding of oxygen to hemoglobin will be discussed, including the oxygen saturation (or dissociation) curve and factors (allosteric effectors) which cause it to shift. Next, a discussion of the effects of carbon monoxide on oxygen binding will be presented. Finally, a description of artificial oxygen carriers will be presented. Most of these topics are covered in standard textbooks [6,10,54,113] and monographs on oxygen transport [112].

you cut your finger and your are bleeding profusely. it appears to be only epidermis. is it true or false? name the anatomical parts to either defend or justify your answer.
Answer:
There aren't any blood vessels in the epidermis; they're located right below it in the dermis, the middle layer of our skin. If you cut yourself and bleed, it means you've torn through the epidermis and left the dermis exposed.
Explanation:
False. If you cut your finger and it is bleeding profusely,
it indicates that the injury has likely penetrated beyond the epidermis, which is the outermost layer of the skin. The epidermis is avascular, meaning it lacks blood vessels, and therefore, injuries limited to the epidermis typically do not result in significant bleeding.
The human skin is composed of multiple layers, including the epidermis, dermis, and hypodermis (subcutaneous tissue). The dermis is the layer beneath the epidermis and contains blood vessels, nerve endings, hair follicles, and other structures. When a cut or laceration reaches the dermis, it is more likely to cause bleeding.
Bleeding occurs when blood vessels are damaged and rupture. The presence of profuse bleeding suggests that the injury has affected blood vessels in the dermal layer or possibly deeper tissues.
To defend or justify this answer, we can refer to the anatomical knowledge of the skin's layers and their characteristics. The epidermis is primarily composed of epithelial cells and does not contain blood vessels. It acts as a protective barrier against external factors. In contrast, the dermis contains blood vessels, and injury that reaches this layer would disrupt these blood vessels, leading to bleeding.
Therefore, if the finger is bleeding profusely, it is likely that the injury has penetrated beyond the epidermis and reached the dermis, causing damage to blood vessels and resulting in bleeding.

What will happen to plant cells if there were no plasmodesmata?
Answer:
Intercellular transportation would not have occurred if there were no plasmodesmata.
Explanation:
Plasmodesmata are intercellular pores connecting adjacent plant cells allowing membrane and cytoplasmic continuity and are essential routes for intercellular trafficking, communication and signaling in plant development and defense
Exchange of molecules and chemical signals between the two adjacent plant cells will not take place.
What is plasmodesmata?Plasmodesmata forms the connections between the two adjacent plant cells through the exchange of cytoplasmic content.
Plasmodesmata forms channels or pores in the membrane through which the cellular components like endoplasmic reticulum, plasma membrane and cytoplasm of two nearby plant cells are connected.
A connection formed between the plant cells through plasmodesmata facilitate exchange of cellular content. This is important for transport of substances across the cells.
Plasmodesmata facilitate movement of nutrients in plant cells. It is also helpful in transport of proteins and hormones.
Plasmodesmata is also important as it serves the function of cell division in plants. It is formed during cytokinesis.
Plasmodesmata are the type of cell junctions and are similar to gap junctions found in animals.
Therefore, plasmodesmata is dynamic for plants cellular activities.

There are more than 600 muscles in the body that help in moving breathing pump blood and carry things
Muscle problems are conditions that affect the muscles which include the conditions in the question for discussion
A muscle cramp is a muscle problem that involves one or more muscle contraction that takes place suddenly and involuntarily. Muscle cramps are very painful and during the episode of the cramp, the affected muscle cannot be used
The causes of muscle cramps include;
Excessive use or strain of the affected muscleToo much caffeine During pregnancyThe use of certain medicinesDehydration of the musclesPinched nerve or spinal chord injury nerve compressionsInability of blood to easily access the musclesCalcium, potassium, or magnesium electrolyte levels being lowMuscle cramps usually do not cause harm
Tetany is a condition that brings about laryngospasm or spasm of the voice
box, carpopedal spasm, which are spasms involving the wrists, fingers or
feet, and toes, and muscle cramps that causes severe pain. Tetany is
generally caused by hypocalcemia which refers to low blood calcium
levels, the cause of the low calcium levels may be due to
hypoparathyroidism. Tetany is treated by identifying the cause of the
tetany with short term treatment goals being to correct the imbalance by
the introduction of calcium and magnesium supplements
Muscle Fatigue is associated with a symptom of decreased ability of the
muscle to perform (tasks) when needed, usually linked to exhaustion after
undergoing exercises that are strenuous. Fatigue is being experienced
when there is an overall reduction of force behind the movement of the
muscle such that a sense weakness is felt and some task that were easily
done before the fatigue are limited

write about menstrual cycle
Answer:
Menstrual Cycle:-
(1) Menstruation occurs in human, apes and old world monkeys.
(2) Menstruation is bleeding from the uterus of adult females at intervals of one lunar month.
(3) Beginning of menstruation or first menstruation is called menarche.
(4) The beginning of menstruation varies. It usually occurs between 12 and 15 years.
(5) The cycle of events starting from one menstruation till the next one is called Menstrual Cycle.
(6) In human females, menstruation is repeated at an average interval of about 28/29 days.
(7) One ovum is released (ovulation) during the middle of each menstrual cycle.
(8) It is regulated by certain hormones, some of which are secreted by the pituitary gland.
(9) The pituitary gland is stimulated by releasing factors produced in the hypothalamus.
(10) The hormones produced by the pituitary gland influence the ovaries. The hormones secreted by the ovaries affect the walls of the uterus.
Answer:
The human female produces gametes(in the form of ova)that are discharged in monthly cycles. these cycles are called menstrual cycles.
the function of the menstrual cycle is to prepare a favorable environment for the developing feotus if fertilization took place.a single egg(ovum) is normally produced and discharged from one of the two ovaries each month.this is called ovulation.ovulation is just one part of the menstrual cycle.the menstrual cycle lasts about 28 days,but varies from 25 to 35 days.the uterine lining thickens in preparation for pregnancy.if fertilization does not occur,the lining breaks down and is shed as a discharge through the vagina.this is called menstruation.the cycle starts on the first day of menstruation.I hope this helps
